eSIMatrix does not offer any unlimited data eSIM plans for Central America. Travelers who want a higher data allowance can choose from the listed fixed‑data plans available from the provider. For example, a 20GB plan can be purchased for five, ten, fifteen, or thirty days, with prices ranging from $70.00 to $85.50 USD. A smaller 10GB plan is also available for five days at $46.50 USD. These fixed‑data options cover Costa Rica, Honduras, Nicaragua, El Salvador, and thirteen additional countries. If a user’s data usage is very high, selecting one of these larger fixed plans can be more cost‑effective than subscribing to several smaller plans, while still providing a clear data cap and validity period.
